CS43131-CNZR

Digital To Analog Converters Overview

The CS43131-CNZR is a high-performance, dual-channel audio digital-to-analog converter manufactured by Cirrus Logic. It features a 32-bit resolution and utilizes delta-sigma architecture to deliver a dynamic range of 130 dB. The device operates within an analog and digital supply voltage range of 1.66 V to 1.94 V. Designed for surface-mount assembly, it is housed in a 40-pin QFN package measuring 5x5 mm with exposed pads. The component supports I2S data interfaces and functions within a commercial operating temperature range of -10°C to +70°C.

Digital To Analog Converters Feature Summary

• Delivers high-fidelity audio conversion with 130 dB dynamic range using 32-bit delta-sigma technology.
• Integrates two independent DAC channels for stereo output applications.
• Supports standard I2S digital audio interfaces for system integration.

Digital To Analog Converters Applications

• High-end mobile devices requiring premium audio performance
• Portable media players and smartphones

Digital To Analog Converters Procurement Notes

Verify the specific suffix CNZR indicates tape-and-reel packaging when sourcing components. Confirm RoHS3 compliance and MSL level 3 status during procurement planning. Ensure the supplier provides valid traceability documentation matching the Cirrus Logic manufacturer part number for quality assurance.

Digital To Analog Converters Selection Notes

Select this component for designs requiring high dynamic range in a compact form factor. Compare against the CS43131-CNZ variant if tray packaging is preferred over reel packaging. Ensure the host system supports the required 1.66V to 1.94V supply rails and I2S interface protocols for proper operation.

Digital To Analog Converters Part Context

This part belongs to the Cirrus Logic MasterHIFI series, designed for mobile audio applications. It serves as a successor or peer to other high-performance audio DACs in the company's portfolio, targeting markets demanding superior signal-to-noise ratios in space-constrained portable devices.

Digital To Analog Converters Replacement Considerations

The CS43131-CNZ is a pin-compatible alternative differing primarily in packaging format (tray versus reel). Verify that the specific application requires the reel packaging configuration before substituting.
